Disclosed is a noise reduction for bidirectional driver/receiver books, which are matched to the characteristic line impedance by a resistor. The idea is to put the serial resistor of the driver into the Bidirectional Bus (BIDI) path. If the line is quiet, the noise margin is increased due to dissipating a part of the coupling energy at the serial resistor before the receiver.
